PICOSTRAIN PS081 Evaluation System

ACAM PS081 Chip

The PS081-EVA evaluation system provides a complete weighing system made of a main board with LCD and solar panel, up to three plug-in modules, a 10kg load cell platform and windows-based evaluation and assembler software. It offers extensive and user-friendly configuration and evaluation of the PS081 single-chip solution for weigh scales.

The PS081-EVAL system is connected to the PC's USB interface through the PICOPROG programming device.

For a proper use of the evaluation system it is strongly recommended to refer to the current PS081 datasheet.
